Fixing open call in write-catalog.c: address@hidden

[Philipp Thomas]

The next version of glibc will be pickier and rejects the call to open in
msgdomain_list_print:

   inlined from 'msgdomain_list_print' at write-catalog.c:223: 
        /usr/include/bits/fcntl2.h:51: error: call to '__open_missing_mode' 
declared with attribute error: 
        open with O_CREAT in second argument needs 3 arguments

What mode should I pass in order to fix this?:
